Abstract
A surgical instrument for use in suction lipolysis consists of a long, narrow tube having a pointed or tapered closed end, for insertion into the body, and being open at the other end for connection to a source of vacuum. The tube has a side opening adjacent to the closed end for entry of fatty material during use. A passageway is provided, either as a separate passage inside the tube or a separate tube inside or outside the main tube, with an end opening inside the closed end of the main tube beyond the side opening. A handle surrounds and supports the main tube and passageway and includes a manually operated valve for venting the other end of the passageway or separate tube to allow air to enter the closed end portion of the main tube during use for clearing obstruction therein.
